Bug in the SoU (spoiler)

[Schar Shantalla]

I was in the 2nd floor of the Crypt, fighting shadow warriors and stuff like that.

almost in the end Xanos was killed and i left him behind (i don't know if it's only with me, but he is useless, can't hit a thing and only uses his firebal (most of times in creatures that are immune to it). After that i went to face the shadow Lord. But i was surprised that NO ONE IFLICTED DAMAGE ON ME!

Something happened and i became invincible!!!
Have you ever seen it before?

the same thing has happened to me when in the tower thing in the middle of undrentide (approaching the final battle) - for some reason it just kind of shoves you in god mode or something lol. bit annoying really.

as for Xanos - I find all arcane spellcaster henchman are a bit useless in nwn and its expansions so I tend to go more for the cleric types if I take a henchman (which is rarely these days as I prefer going solo). They have better henchman type spells and can do melee too.

I am in the same area and though I am not having a problem being invincible, I am having trouble using the portal. Every time I try to use it, it says that the area is insufficient for the portal. I can't get in to fight the Lich. Can anyone help me?
